Antibody Crossreactivity????

Hi, I have a mouse anti-bovine glutamate dehydrogenase mAb and I'm
curious whether anyone would know whether it will crossreact with Human
GDH. I think the two proteins are fairly similiar but how similiar are
humans with cows???
Please send a reply to my E-mail dsho at med.unc.edu
Thanx for any thoughts.
